area beyond yellowish green clouded with blackish; terminal line 
black, interrupted. Under side whitish; all the wings have a blackish 
discoidal mark and band beyond, the discoidal mark of fore wings 
large and distinct. 
?. Similar, but markings of the fore wing less distinct and the 
outer third of the hind wings almost entirely blackish. 
Expanse, 3, 50 millim; ?, 54 millim. 
Collection number, 1859. 
One example of each sex from Arizan; the male obtained 
March 19th, 1909, and the female July, 1908. 
This species comes very near to D. polyphenaria, Guen., 
but the fore wings are somewhat broader and the hind wings are 
whitish. 
AN EXPEDITION IN SEARCH OF RUSSIAN 
BUTTERFLIES. 
By W. G. SHeupon, F.E.S. 
(Continued from p. 274.) 
Glaucopsyche cyllarus.—Not uncommon at Ialtaand Novorossisk, 
and abundant at Sarepta, where it was seen on our first day, and fresh 
examples kept emerging during the whole time of our visit; evidently 
these were delayed emergences of the first brood and not a second 
brood. The specimens taken were of average size, the females 
entirely brown; both sexes had a maximum of blue scales on the 
bases of the wings underneath, and less than the average number of 
ocelli; the inferiors were in some cases entirely devoid of ocelli. 
Lycaena arion.—This species was common at Sarepta on and 
after May 28th ; it was local but widely distributed, and was always 
found in the vicinity of wild thyme. The race is a handsome one, 
usually the blue lowland form, but a few var. obsewra were taken; 
the black spots on the upper sides are well-developed, and in many 
cases elongated and lanceolate in shape. 
Celastrina argiolus.—Not uncommon at Ialta. First seen as a 
second brood at Sarepta on June 17th; the black spots on the under 
sides are larger than those of Western Europe examples. 
Libythea celtis——This species was not uncommon alongside the 
lower road from Ialta to Gourzoff. The specimens, of course, had 
passed the winter in hibernation. 
Neptis lucilla.—lt was one of the most fascinating experiences of 
our stay at Sarepta to see the abundance of this graceful species, 
usually so rarein mid-Hurope. I am aware that one or two localities 
there, including Botzen, produce it in some numbers, but not, I think, 
in anything lke the abundance that it is found on the Volga. 
Everywhere in and around woods it swarmed to such an extent that 
there were often ten to a dozen specimens within a yard or two of 
one. Theonly locality in which I had previously met with N. lucilla 
was Herculesbad, where it was so rare that my two dozen specimens 
involved something like an 18,000 ft. climb, At Sarepta any day at
